                         BACKGROUND OF THIS STATEMENT

      This Amendment No. 1 to Schedule 13D relates to the ownership by EOI Corp.
(the "Reporting Person"), a Pennsylvania corporation, of 1,109,406 shares (the
"Shares") of common stock, no par value, of Escalon Medical Corp. (the
"Issuer"), a California corporation. The Reporting Person was formerly known as
Escalon Ophthalmics, Inc., and the Issuer was formerly known as Intelligent
Surgical Lasers, Inc. In November 1997, the Issuer effected a one-for-four
reverse stock split (the "Reverse Split"), as a result of which each shareholder
became the holder of one share of the Issuer's Common Stock for every four
shares owned before the Reverse Split. References in this Amendment No. 1 to
shares of Common Stock of the Issuer have been adjusted to reflect the Reverse
Split.

      On October 2, 1995, the Board of Directors of the Reporting Person adopted
a Plan of Reorganization, Complete Liquidation and Dissolution (the "Plan of
Liquidation") providing that: (i) the Reporting Person would transfer
substantially all of its assets and certain of its liabilities to the Issuer in
exchange for shares of the Issuer's Common Stock (the "Asset Acquisition"),
which occurred on February 12, 1996; (ii) after the closing of the Asset
Acquisition, the Reporting Person would continue in existence for the sole
purpose of winding up its affairs, and that it would not thereafter engage in
any business activities other than activities related to the implementation of
the Plan of Liquidation; (iii) the Reporting Person would take all necessary
action to settle and discharge, or otherwise provide for, all of its remaining
liabilities, primarily through the delivery of shares of the Issuer's Common
Stock received in the Asset Acquisition and/or through the sale of any or all of
such shares and the application of the proceeds of the sale of such shares to
the payment of the Reporting Person's remaining liabilities; (iv) upon the
settlement and discharge of, or other provision for, all of the Reporting
Person's liabilities, the Reporting Person would transfer all of its remaining
assets, including the transfer in kind of any shares of the Issuer's Common
Stock then owned by the Reporting Person, to its shareholders in accordance with
their respective rights and interests (less any assets retained as reasonable
provisions to meet claims, including unasserted, contingent, conditional or
unmatured liabilities or expenses, and specifically set aside for such purpose);
and (v) the Reporting Person would thereafter dissolve as a corporate entity.

      The Plan of Liquidation was approved by the Reporting Person's
shareholders on January 19, 1996. Thereafter, on February 12, 1996, the
Reporting Person transferred substantially all of its assets and certain of its
liabilities to the Issuer in exchange for shares of the Issuer's Common Stock in
the Asset Acquisition. The Reporting Person has not conducted any business
operations since the Asset Acquisition was consummated.

      In furtherance of the Plan of Liquidation and in order to permit the
Reporting Person to discharge its most significant remaining liability, the
Reporting Person has commenced an offer (the "Exchange Offer") to the holders of
its 10% Convertible Subordinated Notes due October 31, 2000 (the "Notes") to
exchange shares of common stock of the Reporting Person for the Notes. If the
Exchange Offer is consummated, the Reporting Person intends to complete the Plan
of Liquidation in February 1998, which will include (i) either the transfer of a
portion of the Shares to existing creditors and/or the sale of a portion of the
Shares in market transactions in order to
   4
CUSIP No. 296074305                                      Page 4 of 13 Pages

satisfy its remaining liabilities and (ii) upon the discharge of its remaining
liabilities, including the completion of the Exchange Offer, the distribution of
any remaining Shares to its shareholders in final liquidation. See Item 4 of
this Amendment No. 1 for a description of the Exchange Offer.

consummation of the Asset Acquisition under the Acquisition Agreement. Pursuant
to the Acquisition Agreement, the Issuer acquired substantially all of the
assets and certain of the liabilities of the Reporting Person in consideration
for the issuance to the Reporting Person of such Shares. The Issuer effected the
Reverse Split in November 1997.

ITEM 4.     PURPOSE OF TRANSACTION.

      Item 4 is supplemented and restated in its entirety as follows:

TRANSACTIONS RELATED TO THE ASSET ACQUISITION

      The Reporting Person acquired 1,180,193 shares of the Issuer's Common
Stock in connection with the Asset Acquisition. Concurrently with and as part of
the closing of the Asset Acquisition, the Reporting Person and Genentech, Inc.
("Genentech") entered into a Termination and Settlement Agreement (the
"Settlement Agreement") dated as of February 12, 1996. Pursuant to the
Settlement Agreement, the Reporting Person transferred and caused to be
delivered by the Issuer to Genentech 60,000 shares of the Common Stock of the
Issuer in consideration of (i) the termination by the Reporting Person and
Genentech of a license agreement between the two parties, (ii) the
extinguishment of all right, title and interest of Genentech in $1,737,260
aggregate principal amount of the Reporting Person's convertible notes and
warrants exercisable for the purchase of 227,500 shares of common stock of the
Reporting Person, (iii) the grant of registration rights by the Issuer to
Genentech and (iv) the mutual release by Genentech of the Reporting Person and
Issuer, and the releases by the Reporting Person and the Issuer, respectively,
of Genentech, of certain obligations relating to, among other things, the
Acquisition Agreement, the aforementioned license agreement, the notes and
warrant, and other matters occurring or existing on or prior February 12, 1996.

      In addition, 530,096 Shares (the "Escrow Shares") were transferred to, and
are currently being held in, escrow (the "Escrow") pursuant to the terms of the
Escrow Agreement (the "Escrow Agreement") among the Issuer, the Reporting Person
and PNC Bank, National Association, as Escrow Agent, in order to assure the
Issuer that the Reporting Person will have assets available to satisfy certain
liabilities of the Reporting Person that were not being assumed by the Issuer
   7
CUSIP No. 296074305                                      Page 7 of 13 Pages

in the Asset Acquisition. The Escrow Shares may be released from the Escrow by a
written agreement of the Issuer and the Reporting Person to satisfy certain of
the Reporting Person's liabilities.

      Also, in connection with the Asset Acquisition, the Reporting Person
adopted the Plan of Liquidation. The Plan of Liquidation provides that (i) upon
the closing of the Asset Acquisition, the Reporting Person would continue in
existence for the sole purpose of winding up its affairs, and that it would not
thereafter engage in any business activities other than activities related to
the implementation of the Plan of Liquidation, (ii) the Reporting Person would
take all necessary action to settle and discharge, or otherwise provide for, all
of its remaining liabilities either through the delivery of Shares and/or
pursuant to the sale of any or all of such Shares and the application of the
proceeds of the sale of such Shares to the payment of the Reporting Person's
remaining liabilities, (iii) upon the settlement and discharge of, or other
provision for, all of the Reporting Person's liabilities, the Reporting Person
would transfer all of its remaining assets, including the transfer in kind of
any Shares then owned by the Reporting Person, to its shareholders in
accordance with their respective rights and interests (less any assets retained
as reasonable provisions to meet claims, including unasserted, contingent,
conditional or unmatured liabilities or expenses, and specifically set aside for
such purpose) and (iv) the Reporting Person would thereafter dissolve as a
corporate entity.

      Pursuant to the Registration Rights Agreement dated as of February 12,
1996 between the Issuer and the Reporting Person (the "Registration Rights
Agreement"), the Reporting Person has also been granted certain demand and
piggyback registration rights. See "Subsequent Developments" below for a
description of certain registrations effected under and modifications made to
the Registration Rights Agreement.

      As a result of the Asset Acquisition, and as contemplated by the
Acquisition Agreement, three directors of the Issuer, Dieter Broska, Heinz R.
Gisel and Ann H. Lamont, resigned from the Board of Directors of the Issuer, and
Jay L. Federman, Richard DePiano, Jack M. Dodick and Sterling C. Johnson were
elected to serve as directors of the Issuer. Currently, Dr. Federman, Dr. Dodick
and Mr. DePiano are members of the Board of Directors of the Reporting Person.
Following the consummation of the Asset Acquisition, the Issuer's Board of
Directors consisted of Robert J. Kunze, Anthony B. Evnin, Jay L. Federman,
Richard J. DePiano, Jack M. Dodick and Sterling C. Johnson. Mr. Kunze, Dr.
Federman, Dr. Dodick and Mr. DePiano are the current directors of the Issuer,
and Mr. DePiano is the Chairman of the Board and Chief Executive Officer of the
Issuer. There is no continuing obligation under any contractual arrangements to
cause such persons to be nominated or elected as directors of the Issuer. The
Reporting Person is entitled to cumulate its votes in the election of directors
under the provisions of the California General Corporation Law. Inasmuch as the
Reporting Person owns approximately 42.2% of the outstanding shares of the
Issuer, such cumulative voting rights will permit the Reporting Person to elect
a certain number of nominees as directors of the Issuer. Also, its percentage of
ownership will permit the Reporting Person to cast a significant number of votes
with respect to other matters presented to the Issuer's shareholders for their
consideration and vote.
   8
CUSIP No. 296074305                                      Page 8 of 13 Pages

      As reported above, three directors of the Reporting Person are also
directors of the Issuer, and certain officers of the Reporting Person are
officers of the Issuer. Such persons may take actions from time to time in their
respective capacities as officers and directors of the Issuer relating to the
management and control of the Issuer that differ from the current intentions of
the Reporting Person acting in its capacity as a shareholder of the Issuer.

SUBSEQUENT DEVELOPMENTS

      The Shares are the Reporting Person's only significant asset and will be
the sole source of payment of its liabilities.

      The liabilities of the Reporting Person currently include: (i) obligations
under $3,116,810 aggregate principal amount of the Notes as of January 14, 1997
(including the Notes held by Dr. Federman, Mr. Johnson, Dr. Dodick and Sandhurst
as described under Item 2 above) with respect to which the Reporting Person has
commenced the Exchange Offer described below; (ii) obligations under a $150,000
principal amount note payable to, and warrants to purchase 315,789 shares of
common stock of the Reporting Person issued to, a third party; (iii) obligations
under a $50,000 principal amount note payable to Sterling C. Johnson; (iv) the
obligations of the Reporting Person under outstanding stock options to purchase
an aggregate of 816,595 shares of common stock of the Reporting Person at
exercise prices ranging from $0.25 to $1.00 per share (including options held by
certain person described under Item 2 above); (v) a warrant to purchase 22,500
shares of common stock of the Reporting Person at an exercise price of $2.21 per
share issued to a third party; and (vi) the liabilities for legal, accounting
and other expenses relating to the implementation of the Plan of Liquidation
and the dissolution of the Reporting Person, including expenses relating to any
sale of Shares by the Reporting Person. While the Reporting Person cannot
accurately predict the extent of these expenses, they could be substantial,
depending on the issues that arise in the implementation of the Plan of
Liquidation, particularly in the event that the Exchange Offer is not
consummated.

      THE EXCHANGE OFFER

      On January 14, 1998, the Reporting Person commenced the Exchange Offer,
pursuant to which holders of the Notes are being offered 2.566 shares of Common
Stock of the Reporting Person in exchange for each $1.00 in principal amount of
the Notes. As of December 31, 1997, $3,116,810 in principal amount of Notes were
outstanding. The purpose of the Exchange Offer is to enable the Reporting Person
to discharge its indebtedness under the Notes so that it can complete the Plan
of Liquidation in February 1998. The Exchange Offer will expire at 5:00 p.m.,
Philadelphia time, on Monday, February 2, 1998, unless the Reporting Person, in
its sole discretion, determines to extend the offer period.

      The Exchange Offer is subject to certain conditions, including the
condition that all outstanding Notes are tendered for exchange prior to the
expiration of the Exchange Offer. If the Exchange Offer is consummated, the
holders of the Notes will become the holders of approximately 7,997,735 shares,
or 40.5%, of the outstanding Common Stock of the Reporting Person.

CUSIP No. 296074305                                      Page 9 of 13 Pages

      If the Exchange Offer is consummated, the Reporting Person proposes to
complete the liquidation of the Reporting Person promptly thereafter by
distributing to the holders of its Common Stock the Shares that the Reporting
Person continues to hold, after the payment of the Reporting Person's remaining
liabilities and the expenses of liquidation.

      THE REGISTRATION RIGHTS AGREEMENT AND PROPOSED
      TRANSFERS AND DISTRIBUTIONS OF THE REMAINING SHARES

      In August 1996 pursuant to the Registration Rights Agreement, the Issuer
registered under the Securities Act of 1933 the offer and sale of up to 100,000
shares of the Issuer's Common Stock, 60,000 shares of which represented shares
of the Issuer's Common Stock acquired by Genentech in February 1996 and 40,000
shares owned by the Reporting Person so as to register for transfer to permit
the Reporting Person to discharge of certain of its liabilities. In August 1996,
the Reporting Person transferred 10,787 shares of the Issuer's Common Stock to a
creditor of the Reporting Person in discharge of certain liabilities of the
Reporting Person at the rate of $5.5624 per share. As a result of such transfer,
29,213 Shares remain available for transfer under that registration statement.

      In December 1997, the Reporting Person agreed with the Issuer not to
exercise its demand registration rights under the Registration Rights Agreement
through and including February 15, 1998, but retained its right to exercise its
